In this thesis, the research on narrowband active noise control (ANC) systems is presented. The effect of the secondary path transfer function on the convergence of the filtered-x least mean-square (FXLMS) algorithm is ...

Acoustic noise problems become more and more evident as increased numbers of large industrial equipment such as engines, blowers, fans, transformers, and compressors are being employed. Active noise control (ANC), in which ...

The time-domain waveform synthesis method for periodic active noise control (ANC) can be implemented using the impulse train as the reference signal. The time- domain periodic ANC was first implemented and analyzed in this ...

Morphological filters are well known for their potential in image noise reduction. Peters recently proposed an attractive morphological image cleaning (MIC) algorithm that preserves thin features while removing noise by ...

The works presented in this thesis focus on the occurrence and effects of measurement noise in feedback active noise control (ANC) systems and propose a new feedback ANC algorithm. In feedback ANC systems, instead of ...

An adaptive delay filter (ADF) for active periodic noise control (APNC) system has been developed in this thesis. An ADF consists of one variable delay and gain, which has the benefit of simplicity that saves computational ...

In this thesis, we focus on a real-time implementation of multiple-channel active noise control algorithms for noise canceling in a large area. The algorithms considered include multiple-channel filtered-X least mean square ...

The performance of a Crosstalk-Resistant Adaptive Noise Canceler (CTRANC) previously proposed by other researchers has been scrutinized and found flawed in dealing with various noise orientations. Quantitative data and ...

This thesis investigates various fast convergence adaptive algorithms for an active noise control (ANC) application. The traditional filtered-X LMS algorithm has been implemented first, and its performance compared with ...
